| 摘 要： | 基于千兆以太网交换控制芯片BCM53114S和物理层芯片BCM54684设计自适应以太网交换机。完成了系统设计设计,包括核心控制模块、复位模块、电源模块、配置模块等,并进行了系统统调测试。本设计突出的特点是千兆以太网对现有10/100 M以太网的兼容性、芯片高度集成、组网简单、具备生成树功能、自动虚拟局域网（VLAN）切割以及快速故障侦测和修复功能。相对同类产品,这里方案芯片整合度很高,模块化架构使得硬件线路设计比较简单,为数据的高速稳定传输和电磁辐射的抑制提供保证。

| Abstract: | The Gigabit ethernet switch based on BCM53114S and BCM54684 chip is designed.The whole system includes core control module,reset module,power supply module,configuring module.The most prominent feature of this design is the compatibility of Gigabit ethernet to the existing 10/100M ethernet.The chips for the system are highly integrated,thus being easy for construction of network with spaning-tree function,automatic VLAN cutting,fast fault detection and recovery.In hardware design of this project,high-integrated PBGA chips are applied in the modular design with good effect of EMC. |
